BLM15HD601SZ1D - Murata Electronics

BLM15HD601SZ1D Frequently Asked Questions (FAQs)

• What is the recommended land pattern for the BLM15HD601SZ1D?
  The recommended land pattern for the BLM15HD601SZ1D is a rectangular pad with a size of 3.5mm x 2.5mm, with a non-solder mask defined (NSMD) pad shape. This can be found in the Murata Land Pattern Recommendation document.
• How do I handle the BLM15HD601SZ1D's high self-resonant frequency (SRF) in my design?
  To handle the high SRF of the BLM15HD601SZ1D, it's essential to consider the parasitic capacitance and inductance of the PCB layout. Use a 4-layer PCB with a solid ground plane, and keep the inductor away from other components to minimize coupling. Additionally, use a series resistor or a ferrite bead to dampen the resonance.
• What is the maximum operating temperature range for the BLM15HD601SZ1D?
  The BLM15HD601SZ1D has an operating temperature range of -40°C to +125°C. However, the inductor's characteristics, such as inductance and Q factor, may vary with temperature. Be sure to consider these variations in your design.
• Can I use the BLM15HD601SZ1D in a high-voltage application?
  The BLM15HD601SZ1D has a rated voltage of 50V. While it can handle high-frequency, low-voltage applications, it's not suitable for high-voltage applications. If you need a high-voltage inductor, consider using a different part number or consulting with Murata's application engineers.
• How do I ensure the BLM15HD601SZ1D meets my design's EMI and EMC requirements?
  To ensure the BLM15HD601SZ1D meets your design's EMI and EMC requirements, follow proper PCB layout practices, such as keeping the inductor away from noise sources and using shielding or filtering components. Additionally, consider using a common-mode choke or a ferrite bead in conjunction with the inductor to reduce EMI.
